European Committee Issues Positive Opinion of Pfizer's Celsentri(R) (Maraviroc) for Treatment-Experienced Patients Infected with CCR5-tropic HIV-1

SOUTH SAN FRANCISCO, Calif., July 20 (HSMN NewsFeed) -- Monogram Biosciences, Inc. (Nasdaq: MGRM ) announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMEA) issued a positive opinion recommending marketing authorization of collaborator Pfizer, Inc.'s (NYSE: PFE ) investigational HIV medication Celsentri (maraviroc) - the first CCR5 antagonist for use along with other antiretroviral agents for treatment-experienced adult patients infected with CCR5-tropic HIV-1.

A final decision from the European Commission, which has the authority to approve medications for the European Union, is expected within months.

Pfizer also noted that 48-week data from the two MOTIVATE clinical trials confirmed 24-week findings reported in February 2007 and led to the positive opinion from the CHMP.

If approved, Celsentri would be the first member of a new class of oral HIV medicines in more than a decade. Monogram's Trofile(TM) Assay has been used to select patients for the drug's clinical trials.

"Information provided by Pfizer to the April 24, 2007 U.S. FDA advisory committee indicates that "the results in treatment-experienced patients with CCR5-tropic versus non-CCR5- tropic HIV-1 provide clinical data validating Monogram's Trofile Assay as an effective and appropriate means to identify patients with CCR5-tropic HIV-1 and who are therefore likely to respond to maraviroc,"" said William Young, Monogram CEO.

"We expect to make our Trofile Assay available commercially in European markets after Celsentri is approved," continued Young. "Outside the U.S., we are partnering with Pfizer where Pfizer is taking the lead in marketing Trofile and we are implementing the necessary logistical arrangements to make sure the assay can be made available in concert with Celsentri. We expect to be ready for commercial availability in as many as eight countries this year, with an additional forty countries in the planning stages."
